Application filed August 7, 1897.

To all whom it may concern.-

Be it known that I, GIUSEPPE PINO, a subject of the King of Italy, and a resident of Genoa, Italy, have invented certain new and useful Improvements in Diving Apparatus; and I do hereby declare that the following is a full,- clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the reference characters marked thereon, which form a part of this specification.

My invention relates to certain novel improvements in diving apparatus for submarine work, and the object is to provide a device of this kind whereby one or more per sons may descend in the Water and there perform the various operations,- such as blasting, recovering wreckage, and the like.

To this end the invention consists in thel construction, combination, and arrangement of the device, as will be hereinafter more fully, described, and particularly pointed out in the. claims.

The same reference characters indicate the same parts of the invention.

The accompanying drawings show my invention in the best form now known to me; but many changes in the details might be made within the skill of a good mechanic vention as set forth in the claims at the end of this specification.

and the figure to the right is an end view of the same. may be detachably secured to the end of the grappling or the drill bar for sponge-fishing, and the figure immediately below is a top plan view ofthe same. Fig. 12 represents a spoon or cup shaped device similarly attached for coral-fishing, and the figure immediately below is a top plan view of the same. Fig. 13 is a side elevation of the propellingmechanism. Fig. 14 is a top plan view of the same.

Referring to Fig. 1, Q represents the globular diving-bell, provided with the eyebolts R R, by means of which it is suspended from a suitable boom or spar on a vessel, as shown in Fig. 4, so that it may be conveniently raised and lowered.

N represents a basket, bucket, or other receptacle suspended from the lower end of a curved arm N, the upper end of which is fixed to the projecting end of a vertical shaft 2, journaled in a stuffing or packing box in the dome of the bell, and the inner end of said shaft is provided with a crank U for manipulating the basket and swinging it around under the grappling-bar. Of course it will be understood that when the basket is filled with the recovered articles the diving-bell, with the basket, may then be raised to the surface and the basket emptied of its con- "tents. without departing from the spirit of my in-.

D represents an auxiliary curved bottom fixed to the lower face of the bell, so as to provide a ballast-chamber D, the shell. D being formed with orifices 3 3, inclosed by a flange B, which encompasses a disk valve D, having a rubber packing F and formed with the transverse orifices 3 and a valve-stem 4, by means of which said valve may be rotated on its axis to bring its orifices in alinement with the corresponding orifices in the shell across the orifices in the shell and close the Valve.

G represents a cylindrical tube or sleeve extending through the bottom of the bell and shell,op en at its lower end and closed at its upper end,and G represents an anchor contained in said tube and adapted to be raised and lowered by means of the chain 5011 the windlass 6 on the horizontal shaft 7, journaled in Fig. 11 represents a rake which or to present the solid portions of the valve the upper end of the tube G. One end of this shaft extends through the tube and into the chamber 0, formed between the bottom of the bell and the floor 8, and the inner end of this shaft is provided with an angle-gear 9, which meshes with a corresponding gear on the lower end of the vertical shaft 10, the upper end of which is provided with an anglegear, meshing with a corresponding gear on the counter-shaft 11, provided with a crankhandle 12 for conveniently manipulating the Windlass from the inside of the bell.

I'I denotes a hand-pump for discharging the water-ballast in the chamber D through the valve M overboard.

F F represent Vertical walls or partitions fixed on opposite sides of the bell above the floor 8 to form an auxiliary ballast-chamber E, and K K denote valve-rods for operating the valves K" K to admit and discharge water-ballast from said chambers.

A represents the manhole, provided with a removable air tight cap A, by means of which access may be had to the interior of the bell.

Z represents a bracket which may be fixed at one or more points in the bell to receive the drill-shaft 13, which extends through the wall of the bell, and its outer end is provided with the usual drill-bit 14.

O and P represent bulls-eye glasses, protected on the outside by suitable wire-netting to prevent breakage, and through them a light may be projected on the work in progress.

The grappling-bar consists of a tube 01, sliding freely through a ball I), provided with a packing-box l5, and m m represent clampscrews for rigidly securing the tube in the ball when desired. The ball I) has a universal-joint movement through the wall of the bell and the collars 1,6 and 17, which are adj ustably secured together by the bolts 18 18, the nuts of which may be manipulated from the inside of the bell, as occasion requires. The collar 17 is formed with an annular packing flange 19, which fits a corresponding groove in the collar 16 to make a water-tight joint.

g denotes a transverse handle fixed on the inner end of the tube (1, and t' represents the packing-gland, through which the cylindrical rod 0 passes, its inner projecting endbeing provided with a crank-handle h for conveniently manipulating it. The opposite end of said rod 0 is screw-threaded to engage a correspondingly-threaded orifice in the sleeve 20, fixed in the tube d, and its extreme endis j ournaled in a diagonal jaw f, having a longitudinal movement in the slot 21, formed in the outer end of the tube, and 6 represents an alined jaw removably fixed on the outer end of said tube by means of the set-screws'n.

When the jaws of the grappling-bar have seized an article, the basket is swung around under the article and the grappling-bar moved in or out, so as to suspend said article immediately over the basket. The jaws are now separated to release the article, which drops into the basket.

Referring to Figs. 11 and 12, 49 denotes the sponge-rake, and 50 represents the spoon or cup for gathering coral. Both of these implements are provided with a shank 51, which may be inserted between the jaws of the grappling-bar, whereby they may be conveniently manipulated.

In Fig. 7 I have shown a rack-bar 23 fixed at one end to the ball 1), and its inner end extends through a guide-bracket X, fixed to the inner end of the tube d. A pinion 2 1 is journaled in said bracket, so as to mesh with said rack-bar, and it is provided with a crankhandle 25, by means of which the tube may be projected and withdrawn at will.

In Fig. 8 I have shown the gripper-jaws formed with overlapping shearing edges for severing cables, hawse-rs, and the like, and the opposite side of the fixed jaw is formed with an ax-blade 26 for chopping purposes.

Referring to Figs. 13 and 14, 27 denotes the propeller-shaft, provided with the ball 28, which has a universal-joint movement in the collars 29 30, and which are similar in construction to those heretofore described for the gripper-bar. The outer end of this shaft is provided with a propeller 31, which may be of any approved form, and the inner end of said shaft is j ourn aled in a bracket 32, having a depending arm 33, the lower end of which is provided with a hand-screw 34, by means of which the bracket may be adj ustably secured to the rail 35 to correspond to the position or angle to which the propeller-shaft may be adjusted. The inner end of this shaft is provided with a suitable pinion 36, which meshes with a gear 37, fixed on the countershaft 38, journaled in the bracket, and this outer end of said shaft is provided with a crank-handle, as shown, by means of which the propeller-shaft is rotated.
